To all whom it may concern/.

Be it known that I, MILTON S. OABELL, a citizen of the United States,residing at Quincy, in the county of Adams and State of Illinois, haveinvented certain new and useful Improvements in Feed-Water Purifiers, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

It is the object of my invention to provide a simple, effective andinexpensive device for purifying feed water as it is introduced into theboiler and adapted to be suspended in the steam space and to be readilyremoved therefrom when it is desired to thoroughly clean the same.

The invention consists of a pan divided into transverse compartments bypartitions extending partially across the pan and forming a circuitouspassage from the inlet end to the outlet through which the feed waterpasses and is subjected to the galvanic action between the partitionswhich are alternately of electro negative and positive material. Itincludes also a blow off pipe extending longitudinally of the pan, anoutlet pipe, and an inlet pipe, all of which are provided with suitablejoints by which the pan may be removed from a boiler.

In the accompanying drawings Figure 1, is

-a longitudinal section of the device in place in the steam space of theboiler. Fig. 2, is a plan view, and Fig. 3, a transverse section of thepan. Fig. 4, is a view of the device in a steam dome.

In the drawings the boiler 1 is representative of any ordinary form andis provided withthe usual form of manhole and closing plate 2.

The purifying pan 3 is preferably of oblong form having upwardlyextending sides 4 forming a shallow receptacle which is dividedtransversely by partitions 5 which are arranged alternately at oppositesides of the pan so as to leave passages 6 to form a circuitous passage.

The feed water pipe 7 extends down through the boiler shell to the inletcompartment 8 and is provided with a sliding nozzle piece 9 adapted tobe raised on the pipe when it is desired to remove the pan.

At the out-let end a nipple 10 is formed and upon this is held adischarge pipe 11 by means of suitable catches 12 which upon "beingdetached permits the pipe to be removed for the withdrawal of the panthrough the man hole. The pan is suspended from the top of the boiler bythe hooks 13 and thus it is adapted to be readily removed for cleaningby detaching the hooks and the discharge pipe and slipping back theinlet nozzle upon the main portion of the feed water pipe. I haveprovided also means by which the pan may be cleared of sediment withoutremoving it from the boiler and this consists sim ply of a blow off pipe14 extending into the boilerand connected with the perforated pipe 15extending longitudinally of the pan along the bottom thereof and throughthe several partitions.

The blow off pipe is provided with a valve 16 and by opening this thesediment in the several compartments between the partitions will passthrough the perforations of the p pe 15 and be blown from the boiler.This plpe 15 is fixed permanently in the pan and inorder that the devicemay be removed a union 17is provided between the lower pipe 14 and thepipe 15 so that these may be uncovered.

In Fig. 4, I have shown the device as applied in a steam dome a:connected with the steam space of the boiler by a pipe 00 which extendsto near the top of the dome and equalizes the pressure therein. The panand the attached parts are identical with those formerly described andall the parts may be removed through the head opening 1 The dischargenipple in this instance fits into the upper end of a discharge pipe .2permanently secured in the boiler and dome. It will be understood thatthe transverse partitions of the pan are alternately of copper or zincand the pan of iron or the pan can be of copper while the partitions areof zinc or this order may be reversed.

I claim as my invention- 1. A feed water purifier consisting of a panadapted to be suspended in the steam space of a boiler and havingpartitions forming a circuitous passage from end to end, said partitionsbeing alternately of an electro positive and an electro negative metal,substantially as described.

2. A feed water purifier consisting of a ,pan

divided into a series of transverse compartthereof extending from thesteam space ments by transverse partitions alternately of through theshell, substantially as described. [0 electro positive and electronegative metal In testimony whereofI affiX my signaturein and a blow offpipe permanently secured in presence of two witnesses.

5 said pan and extending longitudinally there- MILTON S. ()ABELL.

of across the transverse compartments said Witnesses: permanent blow offpipe being adapted to be HENRY E. COOPER, detachably connected with acontinuation WALTER DONALDSON.
